Earthquakes, tsunamis, volcanic eruptions, and extreme weather. Has Earth always been this way? Featuring footage of top geologic hot spots on every continent, the film traces the scientifically-based story of the 4.5 billion-year-old Earth, from the core to the crust and up into the atmosphere.

This is a very informative DVD. It lets you know how the earth got to be the way it is now. Minus the effect humans have had on it. A great show that one can watch over and over and always get something new from it.
